TOBACCO PIPE.

Application filed November 3, 1924. Serial No. 7437,419.A

To all whom t may concern.'

Be it known that I, JASPER VVHITING, a citizen of the United States,residing at Boston, in the county of Suffolk and State of Massachusetts,have invented certain new and useful Improvements in Tobacco Pipes, ofwhich the following is a specification.

This invention relates to pipes of the character used in smokingtobacco.

It. is the general object of the invention to devise a pipe which willafford a cool clean smoke, which can be readily cleaned, and which shallbe so constructed as to prevent the tobacco in the bottom of the bowlfrom becoming wet and soggy. It is an especially important object of thepresent invention to devise a smoking pipe in which the draft can beregulated. lVhile the invention is especially concerned with pipes, manyof the features thereof are also applicable to cigarette and cigarholders.

The nature of the invention will be readily understood from thefollowing description when `read in connection with the ac Referring rstto Fig.l, the pipe there shown comprises a bowl 2 having an integralstem 3 projecting laterally therefrom. This stern is drilled to form arelatively large bore 4; which is connected with the bottom of the bowl2 by a short throat or passage 5. A mouth piece 6 of a common form isremovably secured to the outer end of the stem 3 by means of a reducedshank 7y which fits frictionally within the bore 4.

The hole 8 through this mouth piece and the passa e 5 are both madeabnormally large so t at these holes, together with the bore Ll, permitan excessive draft. Preferably the hole 8 is slight-ly tapered asclearly shown in the drawings. In the common forms of pipes the draft orpull is deteiimined by thesize of the hole or holes through which thesmoke passes, these holes being made sufficiently small in diameter toproduce satisfactory .results rIn the pipe shown the holes or passagesare so large that an excessive draft is permitted, as just stated, butthe draft may be regulated by theadjustmentdof a split pin 9, best shownin Fig. This pin is very similar to a cotter pin and it may be made ofmetal, bakelite, glass, hard rubbeigor any other suitable material. Whenmetal is used a non-corroding metal shouldbe selected, or thepin-Inay bemade of steel heavily plated with nickel. In any event, the legs of thepin are so made and designed that they tend to jspringapart so that whenthe split end of the pin is inserted in the hole 8 it will befrictionally held in any position of adjust-,K

ment longitudinally ofthe hole by its engagement with the walls thereof.

As is well known the flow or draft of It will be evident that i areaand'its length increased. When the pin y ismovedinlthe,oppositedirection the draft isV increased, or, 1n other words, the pull is madecasier and the pipe smokes more freely.

The smoker thus can regulate the draft to make thewpipe more or lessfree smoking, as vhe may'desire at any time. Preferably the legs of thepin 9 are tapered very slightlyin widthLthe free ends of the legs beingy narrowerthan atk any other point in their length.

The large bore l forms a relatively large chamber in which the flow ofsmoke is retarded so that it is allowed to cool. Any moisture whichotherwise would enter the bowl of the pipe through the mouth piece isalso collected or trapped in this chamber and, consequently, the tobaccoin the bottom of the bowl is prevented from becoming wet and soggy. Theentire charge of tobacco in the bowl thus burns even-ly until consumedand the ashes fall readily from the pipe when the smoke is finished.Furthermore, this trapping of the moisture prevents it from being drawninto the mouth of the smoker to his discomfort. The pipe may be veryeasily cleaned, as will be obvious, and the trap el is of suchproportions that the pipe requires cleaning only at relatively longintervals. By inserting one leg of the pin 9 in either of the holes 8 or5 these passages may be freed of any accumulations that cannot readilybe blown out.

A somewhat different embodiment of the invention is shown in Fig. 2. Inthis construction the stem l() is made of metal tubing, preferablyaluminum, this stem being joined to the bowl-ll by a ferrule l2 intowhich the stem is threaded. The mouth piece 13 is frictionally held inthe outer end of the stem', as in the construction above described. Thispipe also includes a split pin 9, constructed and mounted in the samemanner as in the pipe shown in Fig. l and performig the same functions.This pipe affords even a cooler smoke than that shown in Figi since themetal stem l()v radiates heat more readily than the wooden stem 3.

rl`he invent-ion may be applied to practically any style of pipe, and,as above indicated, it is also applicable to cigarette and cigarholders. For this reason the term pipe is used in the appended claims ina genericsense to include cigarette and cigar holders.

Fig. et shows a cigarette holder embodying the invention. ln this devicethe "bowl l-l has an integral, stem 15 ext-ending therefrom to whichthemouth piece 16 is connected by a screw joint. The relatively large hole17 through the mouth piece permits an excessive draft, but this draft isreduced by the adjustable split pin 9 which restricts the flow of smokethrough the holder.

In all of the constructions aboveshown the split pin 9, when made ofmetal, will absorb heat from the smoke and therefore reduce to someextent the temperature of the smoke. It will also be appreciated thatthe split pin can readily be cleaned by withdrawing it from the mouthpiece andA wiping it with paper or cloth, at which time,

also, the stem or mouth piece can be cleared of any accumulations.

Thilo l have herein shown the best embodiment of my invention that lhave so far devised, I do not wish to be limited to the exactdetails ofthe construction shown.

Having thus described my invention, what I desire to Lclaim as new is:

l. A pipe comprising a bowl, a stem projecting therefrom, a mouthpieceat the end of said stem, said stem and mouthpiece having abnormallylarge smoke conducting holes therethrough whereby an excessive draft ispermitted, and means stationary while in operation but adjustable toregulate the draft through said holes.

'2. A pipe having a stem with a mouthpiece at the end of said stem, saidstem and f mouthpiece having holes therethrough forming a passage forsmoke, and a device -for regulating the draft through said passage, saiddevice being stationary but being adjustable to regulate said draft.

3. A pipe having a stem with a mouthpiece at the end of said stem, saidstem and mouthpiece having holes therethrough forming a passage forsmoke, and a device in said passage for regulating the drafttherethrough, said device being stationary but adjustable longitudinallyin said passage to vary the draft.

4. A pipe having a stem with a mouthpiece at the end of said stem, saidstem and mouthpiece having holes therethrough forming a passage forsmoke, and a stationary device adjustable in said passa-ge andfrictionally held in its adjusted position for regulating the draftthrough said` passage.

5. A pipe having a stem with a mouth piece at the end of said stem, saidstem and mouth piece having holes therethrough for the passage of smoke,and a split pin adjustable longitudinally in one/ofnsaid holes, the legsof said pin tending to spring apart wherebythe pin is frictionally heldin its adjustedI positionby its contact with the walls of the hole.
